REFiNme-ENeiNe SPECIFICATION forming art of rates Eatefit No. 650,738,dated my 29, 1906. Application filed July 21,1899. Serial No. 724,622.(No model.)

To all whom it 71mg concern: v

Be it known that 1, CHARLES EVERETT'TOR- RANGE, of Northampton, in thecounty of Hampshire and State of Massachusetts, have invented a new andImproved Refining Engine, of which the following is a full, clear,andeiiact description.

The invention relates to paper making machinery; and one object is toprovide a new and improved refining-engine arranged to permitconvenient, quick, and accurate adjustment of the shell and revolvingplug without disturbing the position of the plug and the driv ing-gear,so that the latter always remains jn true alinement with the overheadcountershaft pulley; and a further object is to allow the removal of theplug and shell whenever deemed necessary for repairs and other purposesand without disturbing the drivinggear.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claim.

A practical embodiment of my invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicatecorresponding parts in all theviews.

Figure 1 is a plan View of the improvement. Fig. 2 is a longitudinalsectional side elevation of the same approximately on the line 2 2 ofFig. 1, and Fig. 3 is a transverse section of the same 011 the line 3 3in Fig. 1.

A suitably-constructed bed-plate A is provided withlongitudinally-extending guideways 13, in which are fitted to slideflanges O, projecting from a shell 0, in which ismounted to rotate aplug D, secured on a shaft E, journaled at one end in a thrust-bearingF, supported on the bed-plate A, and the other end of said shaft isconnected by a suitable coupling G with a driving-shaft H, carrying adriving pulley H, connected by belt with other suitable machinery, suchas an overhead counter-shaft pulley for imparting a r0- tary motion tothe driving-shaft H, the shaft E, and the .plug D. The driving-shaft His journaled in suitable bearings I, attached to the bed-plate A, as isplainly indicated in the drawings.

The shell 0 is provided with the usual 1in- C and the plug D is providedwith :the uslial bars or cutters D, and said shell 0, as well as theplug D, is preferably made in the form of a fr stum of a cone, as isplainly indicated in l ig. 2. The heads 0 O of the shell 0 are providedwith stuffing-boxes J J, respectively, through which passes the shaft E,and the head 0 closes the receiving chain; her or throat C of the shell;The throat C is provided oh. the top with a receiving-pipe K, throughwhich passes the paper stuff int-0 said throat C and from the latter tothe plug D and shell C for treatment by the revolving plug. The bottomof the receiving chamber or throat O is provided with a collecting-box Cfor hard substances to settle in to prevent injury of the bars D by suchsubstances; The latter are discharged from time to time from thecollecting-box by means of suitable pipes 0 In order to adjust the shell0 longitudinally relatively to the plug D to compensate for wear of thebars D, I provide the following device: On the outside of the shell 0,preferably at the lower part thereof, is arranged or formed a nut 0 inwhich screws a screw-rod L, mounted to turn in suitable bearingsarranged on the bed-plate A. On the outer end of the screw-rod L issecured a worm-wheel N in mesh with a worm N, secured on the lower endof a vertically-disposed shaft N journaled in suitable bearings on thebedplate A and provided at its upper end with a hand-wheel N under thecontrol of the operator. When the, wear on the bars D has been such thatadj ustment is required to bring the bars in proper relative position tothe inner surface of the lining 0 then the operator turns the hand-WheelN to cause the shaft N and its worm N to turn the worm-wheel N and thescrew-rod L and move the shell 0 longitudinally in its bearings B in thedirection of the arrow at until said lining O is again in properrelation to the outer or peripheral surface of the cutters or bars D.

When it is desired to remove the shell and the plug D, together with itsshaft E, for repairs or for other purposes, it is only necessary todisconnect the shaft E from the thrustbearing F and loosen the couplingG to disconnect the shaft E from the driving-shaft H. The plug can thenbe drawn out of the shell, and, if desired,the latter can be removedfrom its guideways B on the bed-plate A.

In the head C preferably at the bottom thereof, is arranged anoutlet-pipe 0, having a slidable connection in a discharge-pipe P,carried by the bed-plate A and leading to a suitable place of discharge.

By reference to Fig. 2 it will be seen that when the shell 0 is shiftedin the direction of the arrow a, as above explained, then thedischarge-pipe O is free to slide in the pipe P without disconnectingthe two and Without requiring any attention Whatever 011 the part of theoperator.

Having thus fully described myinvention,

pipe slidably inserted therein, as and for the 30 purpose set forth.
